With promulgation and obliging actualization of iec 1000 - 3 - 2 etc . international standards , power factor correction ( pfc ) technique become a hotspot of research in power electronics field . based on average current mode , the paper introduce the design and implementation of a fully digital controlled single - phase boost power factor corrector with fast response . the control - loop circuit is realized using digital control and the corrector can tend to unity power factor , lower current harmonics and high transfer efficiency
本文在平均電流模式控制的有源功率因數(shù)校正技術(shù)的基礎(chǔ)上，設(shè)計(jì)了一種控制電路基于數(shù)字信號(hào)處理器( dsp ) 、主電路采用boost變換器拓?fù)浣Y(jié)構(gòu)的全數(shù)字單相功率因數(shù)校正器，用數(shù)字電路代替?zhèn)鹘y(tǒng)的模擬電路來(lái)實(shí)現(xiàn)對(duì)整個(gè)回路的控制，最終使得校正器具有輸入功率因數(shù)接近于1 、低電流諧波以及高轉(zhuǎn)換效率的特性。
